| 19:01 | Move the test for an (illegal) scalar sub-query that returns more than one column to earlier in SELECT processing in order to avoid an assert() that can happen later on. check-in: a55842cf user: dan tags: trunk | |
| 18:13 | Fix an off-by-one error in the scratch memory allocator. check-in: 5a959160 user: drh tags: trunk | |
| 17:15 | Use sqlite3_mutex_notheld() instead of !sqlite3_mutex_held() inside of assert() statements since the former works when mutexing is disabled while the latter does not. check-in: 2211486b user: drh tags: trunk | |
